Design for project change management

In the pipeline design and construction industry, the construction projects are carried out based upon the design descriptions including design configuration and design attributes. The design configuration and attributes of the projects occasionally have to be modified after the construction has been scheduled or during the construction process, thus resulting in construction project changes. These project changes usually bring significant, negative impacts on cost, quality, and construction schedules of the project. In this research, a new systematic approach is proposed to identifying the optimal design to minimize the potential construction project changes. This research focuses on the aspects of pipeline system design. In the configuration design aspect, relations between design configurations and construction tasks are modeled by matrices. The design configuration that is most independent to the construction tasks is identified based upon Axiomatic Design approach. In addition, estimation of project change cost due to the design configuration changes is also discussed In attribute design aspect, potential changes of design attribute values are modeled by probability distribution functions. Attribute values of the design whose construction tasks are least sensitive to the changes of these attribute values are identified based upon Taguchi Method. In addition, estimation of project change cost due to the design attribute value changes is also discussed. Two case studies are conducted to show that the proposed approach can effectively manage the design and construction changes.
